SHARE incorporates in its many thousand lines of code the mass spectrum of more than 500 hadrons according to the particle data group (PDG 2012) [1]}; hadron decays in more than 2500 channels (PDG 2012); integrated hadron yields, ratios and decay cascades. Its output provides the yields of all (presently \(\sim 30\) ) experimentally observed hadron species, and the physical properties of the particle source at hadronization. Bulk matter constraints such as charge per baryon (for heaviest ions \(Q/B\sim 0.39\) ), and that the net strangeness vanishes \(\langle s - \bar{s}\rangle =0\)  are implemented.
